Musical Notes Blog Post

Every musical note has an associated frequency measured in Hertz (Hz), or vibrations per second. The following table shows the approximate frequencies of the notes in the octave from middle C up to the next C on the piano.

What teachers really want to tell parents

In "What Teachers Really Want to Tell Parents" by Ron Clark explains the fact that teachers are feeling abused because of the parents of their students. The average teacher nowadays only teaches for four and a half years before throwing in the towel. Many of these teacher say that the main reason for their quitting is because of the parents. Parents need to realize that the teacher does not try to get their kid into trouble. "What Teachers Really Want to Tell Parents" by Ron Clark shows that parents don't always know whats right.
This article was disgusting. Parents are so ignorant to the fact that a teacher wont lie to you about your kid. This is crazy. The fact that parents will ask for a witness if their kid does something bad and the teacher says they did is outrageous. This will ruin the hope of anyone becoming a teacher because of the thought that you could be treated badly by the parents of a student. Parents need to realize that they may be ruining the hope and dreams of those who look forward to becoming a teacher a some point. "What Teachers Really Want to Tell Parents" by Ron Clark shows that teacher jobs are a lot harder than we think.

I want to compare cups (two at a time) and tell how many cups it would take until the stack of the shorter of the two cups is taller than a stack with the same number of cups of the taller cup. Comparing, #1 with #2, then #1 with #3, then #1 with #4, then #2 with #3, then #2 with #4, and finally #3 with #4.

Equations of cups:

#1: y=.2 x + 5.5

#2: y=1 x + 4.5

#3: y=1.5 x +7.5

#4: y=.6 x + 9

I found my answers by graphing these equations and writing the ordered pairs.

#1,#2

#1,#3

#1,#4

#2,#3

#2,#4

#3,#4

Sense in the problem it I have to find the number to make it taller I have to round up all the decimals I get.

1-2: x=2 cups Because if you substitute in 2 for x in equations 1 and 2 equation 1's y will be bigger than equation 2's.

1-3: x=no solution because you can't have a negative number of cups and if you just look at them you can tell that it wouldn't work.

1-4: x=no solution because you can't have a negative number of cupsand if you just look at them you can tell that it wouldn't work.

2-3: x=no solution because you can't have a negative number of cupsand if you just look at them you can tell that it wouldn't work.

2-4: x=12 cups Because if you substitute in 12 for x in equations 2 and 3 equation 2's y will be bigger than equation 4's.

3-4: x=2 cups Because if you substitute in 2 for x in equations 3 and 4 equation 3's y will be bigger than equation 4's.
